I'm using xLanguage module, but the topic is not module-dependent.

I managed to assign the chosen language value to each comment by editing one variable in /include/comment_post.php. The value is written to DB in comments' table, com_exparams column, which seems to be unused.

PROBLEM: I could not find the file and place, where the com_exparams value is READ from the DB and assigned to a variable.

Can somebody help me? Without modifying the kernel, if possible.

The rest would be simple: show all comments that mach chosen language (in my case). This could be even done through templates.

Oh well, I managed it myself. Now the comments are filtered by language.

When I choose "english" (xlanguage module), only those comments are displayed which were posted when "english" was chosen.

I added additional variable in /class/commentrenderer.php and assigned a smarty variable in /includes/comment_view.php (didn't know where else).

Comments are still counted in all languages and I have to hack the search and edit more templates, but the main work is done. Pretty close to a real multilingual site now.

Comments can be sorted not only by language using this technique, I guess. However, I'm not sure if the com_exparams column in xoopscomments table is really never used. Will get a surprise someday..

Thank for help, friends
